I concede you are correct on velocities. But that same theory would have all of us buying a 300 Whiz Bang simply due to ballistics. More powder, more sound, more recoil. The 6.5x55, 7mm-08, and 250-3000 seem to exist for a reason. Yes, the HR recoils (to me) significantly more than my 220. The Savage 20 seems to be wildly popular, and for good reason...most people shoot it well. Why? Less recoil than a 12.
That being said, I would like a 12 gauge slug gun too! Once a gun nut, always a gun nut. And I do like my buddy's HR, just a bit heavy. It shoots like a dream though.
